Richard Taylor tried to assist troops stationed here with an ultimately unsuccessful counter-attack against a regiment of black soldiers at Milliken's Bend, while John Hunt Morgan almost crossed into Pennsylvania in an attempt to draw opposing forces from this city. Engagements in a campaign named for this city included the Battles of Champion's Hill and Port Gibson, the latter of which resulted in troops under William T. Sherman turning the city of (*) Jackson into a "chimneyville". Shortly after this city fell, another Union victory in the same theatre was secured in the Battle of Port Hudson. Confederates in this city finally surrendered on July 4th, 1863. For 10 points, name this site of a prolonged siege by Ulysses S. Grant to give the Union control of the Mississippi River.
